She's putting $1 million into an online underwear company called Undeez. Refaeli will be responsible for Biz Dev and marketing for Undeez.

Here's why she's doing it:

"I’m opening an online company called Undeez. The website, undeez.com, launches in November and on it you’ll be able to buy clothes - underwear, socks, and t-shirts for men and women - in very soft, basic fabrics. I started the site with a friend because when I like a pair of underwear, I’ll get 30 pairs of it in the same color. But I don’t have time to go buy underwear all the time. And I had boyfriends who were the same way - they never had time to go buy socks and underwear, that’s for sure! - so this website is great because after subscribing, you get these necessities sent directly to you each month."
